IMPROVEMENT IN SEED-DRLLS yAND CULTIVATORS.

Specification forming part ci' Letters Patent No. 34,98, dated April S,18(52.

To all whom, it 17mg/ concern:

Be it known that I, A. B. TRAVIS, of Brandon, in the county ot' Oaklandand State of Michigan, have inventeda new and Improved Cultivator andSeed-Drill; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawings, making a part of this speeitieation, in Which-Figure l is a side sectional vier of my invention, taken in the line xx, Fig. 2; Fig. 2, a plan or top view of the same; Figs. 3 and l,detached views of a tooth pertaining to the same.

Similar letters ot' reference indicate corresponding parts in theseveral figures.

The object ot' this invent-ion is to obtain a cnltivator and seed-drillthe teeth of which may be readily shifted laterally by the attendant inorder to coliform to any irregularities in the rows of a crop undercultivation, and also to evade obstructions-such as stones, stumps,&c.\vhieh may lie in the path of the teeth.

The invention has l'urther for its object a simple means for regulatingthe depth of the penetration of the teeth in the soil.

To enable those skilled in the art to i'ully understand and construct myinvention, I will proceed to describe it.

A A represent two Wheels, which are placed loosely on an axle, B, havinga dratt-pole, C, attached to its center. On the axle B there is placedlongitudinally a bolster, I), which is retained in proper position bythe guide-pins c a, said pins projecting down from the bolster, one neareach end, and passing loosely through holes in the axle E E are twothumbscrews which pass up through the axle B,'one near each end, andbear against the under side of the bolster. (See Fig. l.)

F is a V-shaped frame, which is formed ot` two oblique bars, b I),connected together at their front ends, and having their back divergingends framed into a cross-bar, c, which is fully equal in length to theaxle B. A crossbar, d, is also attached to the oblique bars b b somedistance in front of the bar c, parallel with it, but not so long. (SeeFig. 2.) The oblique bars b b of the frame F rest on the bolster D, andthe front ends et' said bars are connected by a hinge orjoint, e, to thedraftpole C.

To the cross-bar c there are attached a series of inclined standards, f,each having a tooth, g, attached to its lower end. The teeth g may beot' cast or wrought metal, eachn being provided with a socket, l1., atits upper end to receive the lower ends of the standards f, which are ofWood. The teeth gmay be of any suitable form, and different kinds may beused to suit the character of` the Work to be performed. The form of theteeth used in this particular instance will be fully understood byreferring to Figs. 3 and 4t. The two standards f f of the bar c, Whichare at each side of the center standard, j", have their upper endsfitted in oblong mortises z' in the bal1 c, and said standards aresecured in their mortiscs by keys or wedgesj. (See Fig. 2. These wedgesj may be driven into the mortises t at either side ot the standards f,and this consequently admits of a certain degree ot' lateral shifting ofsaid standards. All or any number of the standardsf may be thus attachedto the bar c. This adjustment of the standard j enables the attendanttoplaee the teeth so that they may Work nearer to or farther from therows of plants under cultivation. The standardsf do not all have thesame degree of inclination, one set, which are secured alternately withthe other in the bar c, being more inclined than the intermediate ones.All the standards are braced by rods It from the cross-bar d.

To the under side of the draft-pole C, near its back end, there isattached a metal bar, G, which extends a triiie back of the axle B, andhas a slot, made in it to receive the lower end of a lever II, the upperend of which is attached to a rock-shaft. I, placed longitudinally inthe frame F, and having handles J attached to it.

XVhen the implement or device is used as a seed-drill, any suitableseed-distributing device is placed on the frame F.

From the above description it will be seen that as the implement isdrawn along, the attendant may shit't the frame F, and consequently theteeth g, either to the right or left by operating the rock-shaft I,through the medium ot' the handles .I J, and it Will also be seen thatthe depth of the penetration of the teeth g into the earth may beregulated as desired by adjusting the thumb-screws E E, thereby raisingor lowering the back part of the frame F.

As before stated, however, any forni of teeth may be used.

Having` thus described my invention, what I claim as new, and desire tosecure by Letters I Patent, is-
